Museum of the Broadcast Television Camera

Notes:-
The Pye Mk3 camera was the first Pye camera to use the Image Orthicon tube. It proved to be a success from the start and the compact camera incorporated many new and novel features, like motor driven turret, iris and servo focus drives. The circuit design was conventional, drawing from their experience with the Mk1 Photicon camera.


Pye had a agreement with the USA company General Precision Laboratories (GPL) who provided engineers to help with the development of the Mk3 and they marketed the camera in the Americas.

 

It is reported that 303 Pye Mk3 were sold with about 100 to GPL in the USA and 80 + to the rest of the world. The early cameras suppied to the BBC were in "BBC Dove Grey" colours.

Pye's philosophy was to provide all the equipment for a broadcast installation from the microphone and camera though to the transmitter and at home, the receiver.
